I am considering buying the Asus P4C800 motherboard which has the "ADI AD1985 SoundMAX 6-channel CODEC" onboard sound. This is obviously going to be far superior than my current soundcard from 1998 (Yamaha Waveforce 192XG) but I was wondering; does 6 channel mean it supports 5.1 or 6.1? I ideally want 6.1 which would mean purchasing the Audigy 2 card and speakers if 6 channel means it will run 5.1. Please help!
